MULTIPLE PUNCH.

SPECIFICATION forming part of Letters Patent No. 734,496, dated J u1y128, 1903.

Application filed October 15 1902. Serial No. 127,395. (No model.)

To a/ZZ whom may concerns,

Be it known that L'JOSEPH H. AMES, a citizen of the United States, residing at St. Louis,

Missouri, have invented a certain new and useful Improvement in Multiple Punches, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference .beinghad to thel accompanying drawings, forming part of this specification, in which- Figure l is a fragmentary side view of the head and a portion of a bed-piece of a punch to which the invention is applied. Fig. 2 is a similar View illustrating in section the construction of additional features of detail. Fig. 3 is a broken plan of the head with the invention applied, and Fig. 4 is a face view of a portion thereof. i

This invention isapplied especially to multiple punches, such as are used in the punching of sheet-metal members to be used in steel-car construction, though itwill be apparent that it is capable of use for a variety of similar purposes; and it consists in certain novel features of construction, combination, and operation of parts, all as hereinafter more fully described, and specifically pointed out in the claims. v

Referring to the drawings, A represents the l yoke or gap in the vertical frame of a multiple punch, of which there is one at each end for supporting and guiding the usual vertica llyreciprocatory head B,= carrying the punches C Within a block D, secured in position upon theunderface of said head B by means of the bolts E, which have the usual enlargement or squared head F, riding in a longitudinal channel Grin said head B to permit of shifting the position of said punchblock D, as well understood.

Upon the bed-plate H is the usual bedblock or casting-.1, provided with channels J with vertically-rising Vslots K, within which ride the bolts K', provided with enlarged heads L and nuts M for securing to said bedblock the dies or female member N of the punch as generally constructed.

It will be understood that the punching 5o members are slidable along the length of the which is permitted by loosening the nuts upon the securing-bolts thereof, after whichsaid nuts are tightened to secure said parts in coincident operative position.

In coperative relation to -the punches C are gags 1, which in this construction comprise slidable members locked in .position between the head B and block D bymeans of one of the bolts E, which passes through the slot or opening 2, whereby said gag` is slidable longitudinally to'l cause the yinner end thereof to fill the gap between the upper end of the punch C and the lower face of the head B, whereby a solid abutment therefor is provided for the operation of punching when de- Sired. Upon the -under face of the projecty ing portion of said gags 1 are provided recesses 3, and between the block D and said gags are held flat springs 4, provided with bent portions 5', which register with said recesses when the gags are withdrawn or thrust home and by the click caused in registering locks the same and indicates to the operator that said gags are properly seated` to cause their respective punches C to `operate or not, as may be desired.

Connected in any convenient manner to the outer ends of said gags are operatinghandles 5, 'which maybeof any convenient or desirable formormaterial, but which are here illustrated as bent iu return-curve, so as to form a convenient handle for the operator and a riser above the outery end-of said gags. Extending across the gap ofythe machine and above said gags is a thrust or disengaging bar of any suitable conformation, in the drawings being represented as an anglo-iron 6, connected at each end to th'e under side of the offsets 7 of the sliding pins 8, upon the upper faces of which pins are provided racks 9, with rwhich engage the segments 10, which segments are keyed to a shaft 1,1, which latter is substantially equal in length with said thrustor disengaging bar 6 and uponthe outer end of which is .rigidlysecuredthe'f weighted lever 12, provided at one endwith the handle 13 and at theother end with the loo bar 6 normally in the position indicated in full lines in Figs. l and 2, wherein the handles 5 are freed from contact therewith and may be pushed in to close the gap immediately above the punches C when desired.

It will be apparent that any number of punches consistent with the size of the machine may be used and that any one or more of them may be placed in operation by the mere insertion of the blocks 1, as has been done heretofore, the bar 6 being out of the way, and that the punch will operate in the usual manner. When, however, it is desired to substitute a new series or part otl a new series of punches, instead of the operator being obliged to manually operate each gag to withdraw the same preparatory to resetting in changed series the handle 13 is grasped and drawn forward, thus rocking its shaft, whereupon the segment will advance the racks 9 upon the upper part of said sliding pins, carrying outwardly said bar G against the handles 5 and projecting said gags outwardly, thus clearing all the punches and leaving the entire set in position to be positioned for the changed arrangement, after which the weight upon said handle will reset the same and its connected parts in their normal position.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a multiple punch, a series of punches adapted to be moved to diiterent positions across the gap thereof, gags adapted to coperate with said punches movable therewith, and releasing means coperating with said gags; substantially as described.

2. In a multiple punch, a series of punches, some of which are adapted to be moved to different positions across the gap thereof, gags movable therewith, and releasing means coperating with said gags; substantially as described.

3. In a multiple punch, a series of slidable punch-carrying means, punches and gags, both of which are movable therein and therewith, and a single member operable to release a series of said gags when in different positions; substantially as described.

4. In a multiple punchingmachine,a series of punches therein movable laterally and longitudinally, means also movablelaterally and longitudinally for securing some of said punches in operable position, and means adapted to release a plurality of said punches; substantially as described.
